  The present invention relates to synthesis, purification and methods to obtain high purity novel 2′-arabino-O-methyl nucleosides and the corresponding phosphoramidites of various arabinonucleoside bases and introduction of such units into defined sequence synthetic DNA and RNA. Various synthetic oligonucleotides, such as HIV integrase inhibitor 14-mer and thrombin binding oligonucleotide, thrombin-1, bearing ara-2′-omethyl modification have been synthesized. It is anticipated the oligonucleotides incorporating these monomers will exhibit biological activities related to antisense approach approach, design of better SiRNA's, diagnostic agents. Similarly, it is anticipated that oligonucleotides incorporating such novel nucleosides will be useful to develop therapeutic candidates designing stable G-quadruplexes and Aptamers for oligonucleotide structure, folding topology, evaluation of biochemical properties and design and develop as therapeutic agents. It is further anticipated that the nucleosides, phosphates and triphosphates of this invention could develop as therapeutic agents.

  本发明涉及合成、纯化和获取高纯度新型2'-阿拉伯核苷-O-甲基核苷和各种阿拉伯核苷基的相应磷酰胺酯的方法，并将这些单元引入到定义的序列合成DNA和RNA中。已合成了各种合成寡核苷酸，例如HIV整合酶抑制剂14-mer和凝血酶结合寡核苷酸，凝血酶-1，带有ara-2'-omethyl修饰。预计包含这些单体的寡核苷酸将展示与反义方法、更好的SiRNA设计、诊断剂相关的生物学活性。同样，预计包含这些新型核苷的寡核苷酸将有助于开发稳定的G四链体和寡核苷酸结构的Aptamers，用于寡核苷酸结构、折叠拓扑、生化特性的评估和设计和开发为治疗剂。进一步预计，本发明的核苷、磷酸盐和三磷酸盐可作为治疗剂开发。
